Comment 97 for bug 63352

I have the same card. It worked pretty well for a while but it has developed a bug. Sound just stops working at odd times. There may have been a regression.
Rob... try the following
modprobe snd-hda-codec
modprobe snd-hda-codec-ca0110
lsmod
Are your modules there? You may need snh-hda-intel too.
Remove the card.
Shut down the computer.
Put the card back in.
Turn on the computer.
Remember, these type of cards (for the moment) are not recognized by the system when they are plugged in. They have to be present on boot.
So, when mine stops working, I have to "tell" the machine that the card's been removed, and then turn it off, put the card in, then turn it back on.
